Lu Yuan, a five-star executive chef, returns to his hometown to help his cousin host a wedding banquet. He waives his labor fee and even pays 50,000 yuan out of pocket for high-end ingredients. However, his aunt Liu Cuifen grabs two buckets of leftover potato peels and insists he pay 100 yuan for the lost animal feed. Furious, he throws down 500 yuan, flips the table, and breaks ties with them. Later, his aunt fraudulently uses his name to organize a one-month baby celebration, causing mass food poisoning, and tries to frame him. Relying on evidence, Lu Yuan strikes back and brings the evildoers to justice.
